Lay down naked spreading your legs wide open. Cup and roll your balls, gently squeezing and caressing them as if to warm they're contents. Preparing for the explosion high into the outside world later on.
For about two minutes roll them in your hands, between your fingers feeling their contents, playing with the soft, wrinkled, supple skin. Squeezing, kneading, massaging your balls, eggs, some more. Both together and separately pulling them apart and squishing them together. Pulling the sack skin firmly but gently, forcefully yet methodically away from your body, letting your nails dig into your skin scratching the skin as you pull away.
